I hAve 12 chicks total ranging from 5-6 wks I just recently had to move my older birds out into a makeshift ( insulated )coop. Even though I was reluctant to do this I ended up putting 1 younger chick in who I though could handle it. She mostly hung around the older birds, she did fine. I was terrified. Lol the next day I had four 5 week olds left inside (one who is my runt) and 2 older 6 week old Silkies. I had originally wanted to wait a week or so until they feathered out more but it was beyond my control they literally HAD to be out of the house and outside. I’m looking out the window right now listening to My runt (Josephine’s) tiny peeps, she does normally do a lot of peeping because she’s always below the rest looking for crumbs until she can work her way up top, which she can she’s very feisty she’s not afraid of the bigger birds. But she’s more than half the size of chicks her age, this is her first night in the outdoor home. Will she and also Silkies be okay? I live in NY so it’s probably low 30s tonight. I have a heat lamp in there which has been working for the other birds but it’s just so cold.
